Title: Semiconductor integrated circuit
Inventor: YAMAGUCHI KUNIHIKO
IPC: H01L27/08
Filed: 1988-05-06
Abstract: PURPOSE:To reduce the number of circuits which are driven in an internal block driving line, to eliminate the distortion of a waveform due to the capacity connection of inter-differential signals and to avoid the increase of a delay time due to the distortion of the waveform by dividing a line into the line of inter-blocks and the internal block driving line. CONSTITUTION:A block is divided into (b)-number and the number of the driving circuits in the block is set to (n). A buffer circuit BC receives an input and generates the differential signals. Transistors Q10 and Q11 drive the driving line of inter-blocks and they generate differential signals OR-m and NOR-m. Latch circuits LC-11-LC-1n in a block 1 are driven by differential signals OR-1 and MOR-1 which are generated in transistors Q12-1 and Q13-1 that receive said signals OR-m and NOR-m in basses, and latch circuits LC-b1-LC-bn in a block (b) are driven by differential signals OR-b and NOR-b, which are generated in transistors Q12-b and Q13-1PREPARATIONb. Since the number of the circuits driven by the differential signals OR-1 and NOR-1 that directly drive the latch circuits can be limited to (n), the occurrence of the distortion of the waveform due to the capacity connection of inter-differential signals can be prevented.

Filed: 1987-05-07
Abstract: PURPOSE:To securely detect a flow of a replenishing liquid to a processing tank by a simple device by disconnecting a conduit which connects a replenishing liquid tank and the processing tank in the middle and detecting the electric feed state of the liquid flowing down at the disconnection position. CONSTITUTION:The conduit which connects the replenishing tank 11 and the processing tank of the automatic processing machine is disconnected into a duct 12 on the side of the tank 11 and a duct 13 on the side of the processing tank, a liquid reservoir 14 is provided at an end part of the conduit 13, and an end part of the conduit 12 is open above the liquid reservoir 14. In this state, when a film which is already exposed is put in the developing machine, a controller operates to drive a quantitative pump P, thereby supplying a prescribed amount of replenishing liquid to respective processing tanks. The replenishing liquid which is discharged from a pump flows down in the reservoir 14 through the conduit 12, but it contacts an electrode 16 halfway, so electrodes 15 and 16 are connected electrically to each other. The presence of the liquid flow is therefore detected. When sucking operation is started after the liquid is discharged by the pump, the liquid flow stops and the electrodes 11 and 16 enter a disconnection state.
